Communication system capable of preventing dropout of data block.

摘要

In a data communication system, even when cycle start data is dropped out, a dropout of a data block can be prevented to effectively utilize a frequency band. In the communication system, more than one data block arrived for every preselected time period is transmitted as a packet subsequent to a communication start signal at a time period next to the time period when the more than one data block has arrived, and then a maximum number of data blocks capable of being transmitted within a predetermined time period is determined.
